The hearing capabilities of the Dromornithidae (Aves), with inferences on acoustic communication and ecology

Journal of Anatomy, EarlyView.
The preservation of bony structures which enclose the hearing organs (ECD) provide a basis for interpreting the hearing capabilities of the extinct, flightless Dromornithidae (Aves). Although the length of the dromornithid ECD was especially short, relative to basicranial length, it conformed to the negative allometric scaling relationships observed in

Morphometric study of the bony labyrinth of the inner ear in the European moles Talpa europaea, Talpa occidentalis, and Talpa aquitania

Journal of Anatomy, EarlyView.
The study investigates the shape of the semicircular canals in the inner ear of three sister mole species—Talpa europaea, Talpa aquitania, and Talpa occidentalis—using geometric morphometrics on 58 specimens. It finds both interspecific and intraspecific variability in canal morphology, but no evidence of sexual dimorphism.

An experimentally informed computational model of neurovestibular adaptation to altered gravity

Experimental Physiology, EarlyView.
Abstract Transitions to altered gravity environments result in acute sensorimotor impairment for astronauts, leading to serious mission and safety risks in the crucial first moments in a new setting. Our understanding of the time course and severity of impairment in the early stages of adaptation remains limited and confounded by unmonitored head ...

Firing properties of muscle spindle afferents in the intrinsic foot muscles and tactile afferents from the sole of the foot during upright stance

Experimental Physiology, EarlyView.
Abstract We review our approach for undertaking microelectrode recordings from the posterior tibial nerve at the ankle, which has allowed us to identify, for the first time, the firing properties of muscle spindle endings in the intrinsic muscles of the foot and of cutaneous mechanoreceptors in the sole during unsupported standing.

Benign paroxysmal positional vertigo

Journal of Indira Gandhi Institute of Medical Sciences
Benign paroxysmal positional vertigo (BPPV) is the leading etiology of peripheral vertigo. It manifests with transient, recurring bouts of vertigo brought on by movements of the head.

Labyrinthine fístulae in chronic otitis media with cholesteatoma [PDF]

, 2003
The chronic otitis media with cholesteatoma (COMC) may evoluate to intracranial and extra cranial complications, including the labyrithine fístulae. In this study, we present the evolution of our patients with labyrinthine fístulae.
